The 25 April 2015 Mw 7.8 Gorkha earthquake and its aftershocks triggered about 25,000 landslides over an area of more than 30,000 km2 in the Greater and Lesser Himalaya of Nepal and China. In order to understand the relation among landslide location, earthquake shaking, topography, tectonic geologic and climatic setting, earthquake-triggered landslides were mapped using high-resolution (<1m pixel resolution) pre- and post-event satellite imagery. Source and runout areas were differentiated and mapped separately. The data accompany an interpretive paper published in the journal Geomorphology. The published products are separate ESRI ArcMap 10.2.2 shapefiles that comprise: (i) mapped landslide source areas, (ii) mapped landslide full areas (source, transport and deposit area combined), (iii) the extent of geographic areas in which mapping was completed, (iv) obscured areas in which the mapping is incomplete because of the lack of clear, undistorted satellite data from post-earthquake dates, and (v) image quality designation for mapped regions. 24,915 landslide areas were mapped in the full20170209.shp file (full areas) compared to 24,795 landslide areas in the source20170209.shp file (source areas). This small discrepancy in total number arises because of image distortion and partial cloud cover. One hundred forty two of the full areas lack an identifiable source area. Additionally, 10 full areas have 2 corresponding source areas because the full area could not be divided into 2 separate runout areas due to image distortion; 12 other source areas do not have corresponding full areas.
